Barney is eight years older than Nemo. In seven years the sum of their ages will be 46. How old is Barney now?.

Final answer:

To partition a number line into fourths, divide it into four equal segments, with each representing 1/4. To decompose 3/4 into 6 equal lengths, divide 3/4 into six parts where each part is 1/8 of the whole.

Explanation:

Partitioning a Number Line into Fourths and Decomposing Fractions

To partition a number line from 0 to 1 into fourths, you would divide the line into four equal segments. Each segment represents a value of 1/4. Now, to decompose 3/4 into 6 equal lengths, realize that each 1/4 is being divided into two parts (since 6 divided by 3 equals 2), which means each part is 1/8 in length. Therefore, 3/4 divided into 6 equal lengths gives us 6 segments, each of length 1/8.

Step-by-Step Solution

Draw a number line from 0 to 1.

Mark off four equal lengths between 0 and 1, each representing 1/4.

Find 3/4 on the number line. It is three of these fourths.

Divide each fourth into two equal lengths to decompose 3/4 into 6 equal parts.

Mark these new lengths on the number line, showing that each length is 1/8.

Answer:

Rate column: 30, 20.

Distance column: x miles for both.

Step-by-step explanation:

Jorden drives to the store at 30 miles per hour. On her way home she averages only 20 miles per hour. If the total driving time takes half an hour, how far does she live from the store?

Fill out the Rate column in the table below.

a = 30

b = 20

Fill out the Distance column.

c = x miles

d = x miles

basically: 30, 20 for first question. x miles for both second

Answer:

855mm

Step-by-step explanation:

The area of the trapezoid can be calculated through the equation,

A = (b₁ + b₂)h / 2

where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given,

A = (25mm + 32mm)(15 mm) / 2

A = 427.5 mm²

Since there are two trapezoids in the necklace, the area calculated is to be multiplied by two to get the total area.

total area = (427.5 mm²)(2)

total area = 855 mm²

Part A: The monthly amount payable by Victoria is $503.75. Option B shows the monthly payment made by Victoria.

Part B: The monthly amount payable by Victor is $276.17.

Interest is defined as the amount of money paid for the use of someone else's money.

Part A:

Given that the amount P is $6500, interest rate R is 13% and time period T is 15 months. The yearly time period is given as,

[tex]T = \dfrac {15}{12}[/tex]

[tex]T = 1.25 \;\rm Years[/tex]

The interest is calculated as given below.

[tex]I = P\times\dfrac {R}{100}\times T[/tex]

[tex]I = 6500 \times \dfrac {13}{100} \times 1.25[/tex]

[tex]I =\$ 1056.25[/tex]

The total amount after 15 months is given as,

A = P + I

A = $6500 + $1056.25

A = $7556.25

This is the amount of 15 months. The amount of one month is calculated as given below.

Monthly Amount = [tex]\dfrac {\$7556.25}{15}[/tex]

Monthly Amount = $503.75

Hence we can conclude that the monthly amount payable by Victoria is $503.75. Option B shows the monthly payment made by Victoria.

Part B:

Given that the amount P is $6800, interest rate R is 13.5% and time period T is 3 years.

The total amount after 3 years is given as,

[tex]A = P (1 + \dfrac {R}{100})^T[/tex]

[tex]A = 6800 (1 + \dfrac {13.5}{100})^3[/tex]

[tex]A = 6800 \times 1.4621[/tex]

[tex]A = \$ 9942.28[/tex]

This is the amount of 3 years or for 36 months. The amount of one month is calculated as given below.

Monthly Amount = [tex]\dfrac {\$9942.28}{36}[/tex]

Monthly Amount = $276.17

Hence we can conclude that the monthly amount payable by Victor is $276.17.

Answer:

Equation of the circle is

[tex](x-4)^2+y^2=12[/tex]

Step-by-step explanation:

We have been given that

center of the circle = (4,0)

Radius of the circle = [tex]2\sqrt3[/tex]

The standard form of a circle is given by

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here, (h,k) is the center and r is the radius. Thus, we have

h = 4, k = 0, r = 2√(3)

Substituting these values in the above equation, we get

[tex](x-4)^2+(y-0)^2=(2\sqrt3)^2[/tex]

Simplifying, we get

[tex](x-4)^2+y^2=12[/tex]

Therefore, equation of the circle is

[tex](x-4)^2+y^2=12[/tex]

Answer:

1. x² + 2x + 2

2. x² + 4

3. x² - 4x + 8

Step-by-step explanation:

(1) ( x+1+i ) ( x+1-i )

= ( x+1 )²- i²  [ Since ( a+b ) ( a-b ) = a² - b² ]

= x² + 1 + 2x - ( √-1 )²

= x² + 1 + 2x + 1

= x² + 2x + 2

(2) ( x+2i ) ( x - 2i )

= x² - (2i)² [ ( a+b ) ( a-b ) = a² b²

= x² - 4i²

= x² - 4 (-1) [Since i² = -1 ]

= x² + 4

(3) ( x - 2i - 2 ) (x + 2i - 2 )

= ( x-2 )² - ( 2i )² [ ( a+b ) ( a-b ) = a² - b² ]

= x² + 4 - 4x - 4 ( i )²

= x² + 4 - 4x - 4 ( -1 )²

= x² - 4x + 4 + 4

= x² - 4x + 8

A zoo has 14 monkeys and 18 chimpanzees.

To write the ratio of numbers x and y we use three ways given below

1. x to y

2. x : y

3. [tex] \frac{x}{y} [/tex]

Now write the ratio in three ways comparing 14 monkeys and 18 chimpanzees.

Let x be the number of monkeys

y be the number of chimpanzees

So ratio becomes

14 to 18

14 : 18

[tex] \frac{14}{18} [/tex]

Answer:

The orientation of the figure has been changed by 90°, but the points are not all rotated around the same center. Translation is involved.

Translation before rotation:

.. translate down 5 units

.. rotate counterclockwise 90° about the origin

Translation after rotation:

.. rotate counterclockwise 90° about the origin

.. translate right 5 units

This can also be accomplished by a double reflection.

.. reflect across the line y=x

.. reflect across the line x=2.5

Or,

.. reflect across the line y=2.5

.. reflect across the line y=x

Answer:

A. [tex]I\approx \$103.16[/tex]

B. [tex]\text{Total payment}=\$1161.16[/tex]

C. [tex]\text{The monthly payment}\approx \$129.02[/tex]

Step-by-step explanation:

We have been given that Devin borrowed $1,058 at 13 percent for nine months.

A. To find the amount of interest paid by Devin we will use formula: [tex]I=Prt[/tex], where,

[tex]I=\text{Amount of interest}[/tex],

[tex]P=\text{Principal amount}[/tex],

[tex]r=\text{Interest rate in decimal form}[/tex],

[tex]t=\text{Time in years}[/tex].

Let us convert our given interest rate in decimal form and time in years.

[tex]13\%=\frac{13}{100}=0.13\\\text{9 months}=\frac{9}{12}\text{ year}=\frac{3}{4}=0.75\text{ year}[/tex]

Upon substituting our given values in interest formula we will get,

[tex]I=\$1058*0.13*0.75[/tex]

[tex]I=\$103.155\approx \$103.16[/tex]

Therefore, the amount of interest paid by $103.16.

B. Since total payment will be equal to interest rate plus amount of interest.

[tex]\text{Total payment}=\$1058+\$103.16[/tex]

[tex]\text{Total payment}=\$1161.16[/tex]

Therefore, Devin's total payment will be $1161.16.

C. To find the monthly payment we will divide total amount by 9.

[tex]\text{The monthly payment}=\frac{\$1161.16}{9}[/tex]

[tex]\text{The monthly payment}=\$129.01722\approx \$129.02[/tex]

Therefore, the amount of Devin's monthly payment is $129.02.
